CATTLE-GUARD.

SPECIFICATION forming part ofLetters Patent No. 723,833, dated March 31,V 1903.

Application filed Februaryl, 1902. Serial No. 94,279. (No model.) il

fo all whom)V iv' nca/ycwern.

Be it known that I, EUGENE COOK, a citizen of the United States, residing at the city of Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Cattle-Guards, of which the following is a specification.

This invention relates to improvements in cattle-guards.

The objects of this invention are, first, toV

provide a cheap and efficient means of retaining parallel wooden bars-intended for use in cattle-guards in position; second, to provide suchastructure adapted for usein connection with means forsupporting serrated protecting bars or rails.

Further minor objects will definitely appear from the detailed description to follow.

I accomplish the objects ot' my invention by the devices and means described in this specification. g

Theinvention is clearly defined, and pointed out in the claims.

A structure embodying the features of my invent-ion is clearly illustrated in the accompanying drawings, forming a part. of this speciticatiomnin which- Figure l is a plan view of acattle-guard" embodying the features of my invention. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged detail transverse sectional view taken on a line corresponding to lines 3 3 of Figs. l and 2. Fig. 4 is a detail transverse sectional view taken-on a line corresponding to lines 4 4 of Figs. land 2.V

In the drawings all of the sectional views, are taken looking in the direction of the little arrows at the ends of the section-lines, and similar letters of reference refer to simi-V lar parts throughout theseveral Views.

Referring Vto the lettered parts of thedraw ings, A represents longitudinal wooden rails, making up the main body of my improved cattle-guard. These are narrowed to an edge at the Icop and widened into a comparatively wide base at the bottom and are adapted to stand on such base with the sharp edges projecting upwardly. These rails are supported on cross-piecesB D. The cross-pieces B are provided with upwardlyprojecting lugs B', arranged in pairs.- The pairs of lugs are separated a distance equal to the space occupied metal.

used the guard has all the advantages of metal by two of the Arails and are adapted to engage the opposite sides of pairs of adjacent rails. A Wedgeblock i3, adapted to drawdown be- 55 tween the adjacent pairs of rails and'in connection with the lugs B clamp the'same in position, is secured to the cross-pieoe B by a bolt C. lt is preferred to form the parts in such a manner that the wedgefpieces B" Will 6.o not quite come in contact with the cross-piece B, so that the-bolt C can be tightened in the event of the shrinking of the wood.

'lo make the guard particularly effective, l'place serrated metal rails A A on top of the 65 wood rails A at one end, the upper portions of the Wood rails being cut away to accommodate the same, as clearly appears in Figs. 2 and 4.

Beneath the eut-away portions of rails A 7o cross-pieces D are substituted for cross-pieces B, and above these cross-pieces cross-bars E are laid on top of the rails. These cross-bars have pairs of oppositelyfacing shoulders, against which the serrated metal rails A' A 75 are secured by clip-pieces E', which are secured to thecross-bars E by bolts c. When assembled in this way, they are clamped on top of the rails A bymeans of bolts e, which are passed through the cross-pieces E and. D. 8o

The cross-pieces D are provided with seats for the rails, and the rails are clamped into these seats by means of the cross-bars E and bolts e described. The cross-bars D are provided for use in connection with the serrated metal-rail construction as being slightly more economical, although, if desired, the crossbars B maybe used in this connection.

This makes a guard which is very effecti-ve and cheap to manufacture, because the 9o wooden rails A are much lessexpensive than When the serrated metal rails A are rails, as for a distance at the outer end or the highway end of the guard these wood rails are protected or armed on their upper edge with the serrated metal rails A.

Having thus described myinvention, what I claim as new, and desire to secu re by Letters Patent, is j q i? 1. In acattle-guard, the combinat'ilnof the rails A, Wide at the base` and Vnarrow at the top; a cross-piece B with lugs B projecting upwardly therefrom against the opposite sides IOO ofpairsofadjaeentrails; andawedgeshaped Eshaped pieces with means of securing the Io pieeeB inserted and clamped between the i same between the rails of each, as speeied. rails of each pair and clamped to the oross- I In witness WhereofI have hereunto set my har B below, coasting for the purpose speey hand and seal in the presence of two Witfied. nesses.
